Answer
Unfortunately, this is not possible and intentionally unsupported due to the security risk of losing access to the RS1xx Sensor in the field. This restriction applies to all changes involving packet formats / types, channels, frequencies, data rates, operating modes — both confirmed and unconfirmed— as well as DevEUI, JoinEUI (formerly AppEUI), AppKey, and the backlog feature. These settings are designed to be configured exclusively through the Bluetooth Low Energy (BLE) interface using our Sentrius RS1xx Sensor mobile app, available at https://www.ezurio.com/using-sentrius-rs1xx-sensor-app, for iOS and Android smartphones. This approach is designed and will help ensure a secure and consistent device setup process during the initial commissioning and deployment stages.
